4.1.3.2 Setting Up Real Antipassback
Real Antipassback operation is defined in the Time Zone Configuration Screen. To apply Real Antipassback
to card users, you must define Antipassback in the Time Zones used to create their Access Groups. Note
that Time Zone 1 is not affected by Antipassback, so don’t assign a card holder with Antipassback to an
Access Group using Time Zone 1.
If Antipassback-exempt card users require the same access schedule as those who are subject to
Antipassback, you may have to create additional Time Zones and Access Groups that are identical except
for their Antipassback definitions.
1. Identify the Access Groups to be affected by Real Antipassback, and determine which Time Zones are
used to create those Access Groups.
2. Select the desired Real Antipassback option for the appropriate Time Zones. Choose from:
Real Hard — Cards must be used alternately at IN, then OUT readers or be denied access.
Real Soft — similar to Real Hard, except that access is granted – if card is used twice in succession at
an IN reader or OUT reader, an exception is logged for administrative use.
None — Antipassback is disabled for this Time Zone.
Click on the appropriate radio button, click on Save, then Send.
3. Add Readers to IN/OUT Reader Groups. Click on SK-NET
TM
Explorer, select the desired Location, then
click the “+” button to expand the All Readers Group.
To designate a reader as Antipassback IN, simply “copy” it from the All Readers group by clicking
on the reader icon and dragging it into the IN Readers Group. To designate a reader as Antipassback
OUT, “copy” it from the All Readers group by clicking on the reader icon and dragging it into the
OUT Readers Group.
4. If you are using Remote Readers for Antipassback or if you need to set a Daily Antipassback Forgive
time, you must use the Reader Configuration Screen. To configure all readers at one Location alike, right
click on the All Readers, select Properties and select Configuration. (NOTE: After you make changes to
the Global Reader Configuration, verify that all information of this screen is correct. When you click on
Send all these settings will be sent to all the readers.) To configure a single reader, click on SK-NET™
Explorer, then double-click on the desired reader icon. Select the Configuration tab, Click on Edit, make
the desired settings and Send.
Remote Reader Type — This allows you to set the Antipassback type for a remote reader connected to
a 28SA-Plus. Set type to IN, OUT or NONE, click on Send, then Close.
Daily RAPB Forgive Time — This can be set to any hour, 0 - 23 (Military Time). This automatically resets
all cards that are subject to Real Antipassback to Neutral IN/OUT status. Once “forgiven,” cards will be
granted access regardless of their previous status. It is recommended to set Forgive Time via Global
Reader Configuration or to set all affected readers alike. To set, click the ON button, enter the time, click
Send, then Close.
4.1.3.3 Timed Antipassback
Timed Antipassback prevents card reuse by temporarily voiding the card when it is first used at the reader,
until a pre-defined time period expires. Timed Antipassback is recommended when the area to be controlled
has only one entrance, or if it is not possible to have networked readers at every entrance and exit. The
disadvantage of Timed Antipassback is that in a multi-reader facility, the unauthorized person can
circumvent antipassback by simply seeking access at another entry.
The Antipassback Time Period applies only at a specific reader and any connected remote reader; the time
period is not broadcast to other readers on the network.
4.1.3.4 Setting Up Timed Antipassback
Timed Antipassback operation is defined in the Time Zone Configuration Screen. To apply Timed Antipassback to
